Definitions

  • This invention relates to photoelectric facsimile transmitters which scan a document or other original graphic record and generate electrical signals similar to line-by-line television signals for reception by a recorder such as an electrolytic facsimile recorder which electrically reproduces the original graphic record.
  • a recorder such as an electrolytic facsimile recorder which electrically reproduces the original graphic record.
  • the facsimile there are many scanners designed to reproduce records of standard sizes, but there is a need for apparatus for scanning only a portion of original records.
  • a banking system when a checking account is opened in one bank branch an authorized signature for withdrawal of checks is subscribed on a signature card by the depositor.
  • the depositor's checks may be presented at another bank branch or to a teller remote from the signature card file.
  • the signature card can be transmitted by facsimile to the teller for comparison of the signatures on the card and on the check.
  • normal facsimile transmission of the signature card even at high transmission speed, is too slow for normal volume of check cashing transactions.
  • one object of the present invention is to provide a facsimile transmitter which eliminates time for transmitting other than a selected portion of a graphic record, such as the signature portion.
  • a further object is to provide apparatus in which the bank clerk or other operator can easily select the limited portion to be transmitted, and can view the selected area, face up, in position for transmission.
  • a still further object is to provide a facsimile scanner which can transmit a whole document as well as selected portions thereof.
  • means are provided for adjusting the limiting means from carriage movement limiting position.
  • FIG. 1 is an isometric view, partly broken away, of a facsimile transmitter according to the invention with its graphic record carriage at innermost position;
  • FIG. 2 is a side elevation of the transmitter, partly broken away;
  • FIG. 3 is a plan view, partly broken away
  • FIG. 4 is a front elevation of details of the transmitter
  • FIG. 5 is an isometric view showing the transmitter with its graphic record carriage in outer position
  • FIG. 6 is an electrical wiring diagram.
  • a facsimile scanner exemplary of the present invention comprises a main frame 1 including a base 2 and a chassis 3 for slidingly supporting a document carriage 4 with a top platen surface 6.
  • a housing 5 encloses the frame and base.
  • the carriage 4 has a transverse stringer 10 carrying shoes 7 sliding in tracks 8 on the chassis 3 (FIG. 4).
  • a carriage motor M1 on the frame 1 drives a plastic belt 9 around an idler roll 11 (FIGS. 3 and 4).
  • a spring clip 12 depending from the carriage stringer 10 frictionally grips the belt with slip coupling action which normally allows the motor to drive the carriage linearly from its inner position shown in FIGS. 1 to 4 to its outer position shown in FIG. 5, but which allows the carriage to be moved manually from its outer position independently of the motor when stopped or running.
  • a spring detent 15 for receiving and clipping flatwise a document 13 such as a signature card with a signature area 14 indicated by cross hatching.
  • the detent 15 has arms 16 which serve as a frame for the signature area or any other selected area of a document.
  • the document is inserted under the detent face up with the selected area framed by the detent or other indexing marks on the platen.
  • the carriage 4 is in its outer position shown in FIG. 5 prior to transmission and the face up area 14 framed by the detent is easily visible to the operator as shown in FIG. 5.
  • the control circuit includes a scanner start circuit 22 controlling a motor M2 driving a rotary facsimile scanner 23.
  • the start circuit starts the rotary scanner, which in a well known manner transmits framing pulses to the remote facsimile recorder.
  • the scanner control circuit also includes a time delay circuit 24 which delays energization of the carriage motor M1 for the synchronization period. The motor then drives the carriage back to its outer position carrying the document on the carriage platen in a planar path under a scanning assembly 26.
  • the scanning assembly 26 includes a scanning head 27 enclosing a photoelectric tube 28, and rotary helical or spiral scanning mechanism, not shown but well known in the facsimile art.
  • the photoelectric tube 28 and its associated lenses view the carriage platen 6 through a hood 31 along a plane P folded by a mirror 29 to a scan line L extending transversely of the carriage platen (FIGS. 2 and 3).
  • a scan line L extending transversely of the carriage platen
  • the scanning apparatus so far described is generally capable of scanning a whole document as well as a selected portion thereof it would be wasteful to limit the scanning capability to an area smaller than a whole document.
  • large volume transactions such as check cashing there is no time or need to scan a whole document.
  • a selected area of a document can be scanned in a minimum of time or, alternatively a whole document can be scanned.
  • an adjustable stop 30 in the shape of a bell crank with a nose 32 is pivotally mounted at 33 on the side of the chassis 3.
  • a tie rod 34 extending from a front panel knob 36 to the stop 30 adjusts the nose 32 of the stop between the vertical position shown in FIGS. 2, 3 and 4 to a horizontal position.
  • the stop nose 32 In its vertical position the stop nose 32 is in the path of a lug 37 under the carriage 4 where it arrests inward movement of the carriage such that the selected document area 14 lies just outside the scanning line L.
  • the selected area is one half an inch lengthwise of the carriage, the stop 30 being equally spaced from the lug 37. Scan of a one half inch area can be completed in eleven seconds, whereas a complete document six inches long would require 1.7 minutes.
  • the full document can, however, be transmitted by manual adjustment of the stop to horizontal position out of the path of the carriage lug 37.
  • the carriage may then be pushed to the innermost position for a scan of nine inches substantially the full length of the platen.
  • a document 13* of intermediate length may be scanned in less than the time for the longest document by pushing the carriage only part way toward innermost position, the depth to which the carriage should be pushed being indicated by the framing arms 16 or other index marks.
